People are simply guilty of blindly believing their favorite piece of software, apparently ignorant of the limitations of non-integrating propagation. When an asteroid is well within the sphere of influence of the earth, it is hardly appropriate to use a program that's based on Kepler's two-body equations... --Rob -----Original Message----- From: meteorite-list-bounces at meteoritecentral.com [mailto:meteorite-list-bounces at meteoritecentral.com] On Behalf Of Sterling K.
